VPC" Pro Component subwoofers in order to intrqduce a series of loudspeakers
offering unparalleled value in the car audio market. The VPC performance standards were
increased yet we were able to drive the speaker costs down using improved manufacturing
techniques and high technology materials.
Unique to the new Ve/ocityTMwoofers
advantages of this design include the improved loudspeaker configuration flexibility and the
potential performance increases from higher power handling. Best of all, the consumer can
often achieve the performance of two single coil subwoofers with one VPC dual voice coil
speaker.

speaking, 9 5 % of the car audio subwoofer installations made today really don't need $400
woofers with 100 oz magnets! The VPC series woofers were designed for HIGH POWER
HANDLING LEVELS, HIGH SOUND PRESSURE LEVELS, and FLEXIBLE INSTALLATION
CHOICES.
HIGH POWER HANDLING was achieved
through a new ultra-linear long-throw
suspension with "bottomless" back plate
design allowing for tremendous cone
excursion without voice coil damage. The
new rigid spider design (Blaupunkt
trademarked as "SPIDERMAX") renders
spider tears a thing of the past. Double
thickness compressed foam surrounds
offer linear cone movement without tearing
from over-excursion. New Strontium
Ferrite magnets yield smaller magnet sizes
without reduced magnet strength but
retain their magnetic power far beyond the
expected life of the woofer. Four layers of

Fahrenheit without damage. New basket designs prevent the back of the cone from
slapping the steel frame thus avoiding acoustical distortions and possible cone damage.
Rear vented pole plates allow fresh air to move in from behind the woofer to cool the voice
coil plus help prevent dust cap "popping" at the excursion limits.
